Assembled friction metal damper with earthquake monitoring and staged energy dissipation functions
The invention discloses an assembled friction metal damper with earthquake monitoring and staged energy dissipation functions. The assembled friction metal damper comprises an I-shaped steel plate, two friction plates, two U-shaped steel plates and energy dissipation elements, and the energy dissipation elements comprise a first curved variable cross-section I-shaped energy dissipation element anda second curved variable cross-section I-shaped energy dissipation element. One side of the I-shaped steel plate is connected with the first curved variable cross-section I-shaped energy dissipationelement through bolts, the two U-shaped steel plates are arranged on the two sides of the I-shaped steel plate correspondingly, the two U-shaped steel plates are connected with the I-shaped steel plate into a whole through bolts, the friction plates are clamped between the U-shaped steel plates and the I-shaped steel plate, and the two U-shaped steel plates are further fixedly connected with the second curved variable cross-section I-shaped energy dissipation element through bolts. The assembled friction metal damper has the beneficial effects that two deformation mechanisms of friction and metal deformation are used for dissipating energy to provide reasonable in-plane and out-of-plane rigidity and energy dissipating for the damper, and the overall performance level of the structure can be monitored in real time through strain sensors.
